Chocofly DG800: installation servos and motor (FES)

As mentioned in my earlier post, this is a pretty quick build. The servos in the fuselage and wings are installed. I used the Chocomotion 10 and 8mm Servos with the new Chocomotion LDS system, all of which I’m familiar with from previous builds and which work perfectly. There is no play on the wing control surfaces whatsoever and I’m able to use the full range of all servos, with sufficient throw.

I also installed the motor bulkhead. I was a bit nervous about this one, as Chocofly now uses MIGflight motors with a new type of bulkhead that’s glued in from the front. This no longer allows me to use my usual method for installing the motor. It turned out to be easier than feared. I first did a rough cut and then sanded back the nose, repeatedly fitting the motor and bulkhead to see if the fit was right. In the end I fixed the bulkhead (with motor) in the right position using a few dots of 5 minute epoxy. I then removed the motor, covered the front of the bulkhead and the nose of the DG with wax tape and fixed the plane with the nose down. Using a small pencil I first added some white coloured resin on the sides of the bulkhead (from the inside), wrapped in a thin carbon roving and then filled up the rest with somewhat thickened epoxy resin. Curious to see how it comes out tomorrow. I do hope that I got the downward angle of the motor (usually somewhere between 3 and 4 degrees) in the right range.
